OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 742,916, dated November3, 1903.

Application filed March 18, 1902- .Serial No. 98,842. (No model.)

To aZZ whom i2; may concern:

I Be it known that I, HARLEY LEROY SHER- WOOD, a citizen of the UnitedStates, residing at Oakland, in the county of Alameda and State ofCalifornia, have invented certain new and useful Improvements inKerosene-Oil Burners, of which the following is a specification.

My invention relates to improvements in kerosene-oil burners fordomestic stoves or ranges, for generation of steam for propellingautomobiles, or for other analogous uses, the object of my inventionbeing to provide a device of this character which shall be cheap andsimple in construction, which shall be compact in form and size, whichcan be readily cleaned without requiring expert assistance for thatpurpose, and which shall be strong and durable and not liable to get outof order.

My invention therefore resides in the novel construction, combination,and arrangement of parts for the above ends hereinafter fully specified,and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view ofmyimproved oil-burner. Fig. 2 is a horizontal section thereof throughthe oil-channel. Fig. 3 is a longitudinal section on the line A A ofFig. 2. Fig. 4 is a cross-section on the line B B of Fig. 2. Fig. 5 is aperspective view of the spreader detached. Fig. 6 is a similar viewof asupport for the spreader. Fig. 7 is a similar View of the base-plate.Fig. 8 is a perspective view of a modified form of burner.

Referring to the drawings, it will be seen that the burner properconsists of a single casting having straight sides 2 and ends 3 andhaving its sides joined to the center by a bridge 4. In making saidcasting the sides and ends are cored completely through from end to end,so that the casting when taken from the mold has correspondingpassages 56 in said sides andends. Said passages cross each other and open intothe ends and sides of the casting, so that by closing the ends thereofthere is formed in the casting a peripheral channel making a completecircuit. An opening Z is also made from one side of the burner into themiddle of the side conduit 5, and into said opening is screwed the endof an oilpipe 8. The oil therefore entering through said oil-pipe 8divides and flows to the right and left along the side passage 5 in thedirections shown by the arrows and then around by the end passages 6 andthen flows to the middle of the side passage 5 opposite to that at whichit enters. The two streams of oil at this point unite and pass along achannel 9, formed in the bridge in casting and extending to the middleof said bridge. It then falls into a downward extension 10, .dependingcentrally from said bridge. In the opposite sides of said extension 10are screwed two gas-pipes 11, closed by caps 12 and having apertures 13,through which the gas can escape. The gas emerging from said gaspipesstrikes the wings 14 of a spreader 15, resting upon supports 16, laidupon lugs 17,

formed in one piece with the burnercasting.

By means of the wings of this spreader the flames are deflected upon theburner, thereby heating the entire mass, and thus'vaporizing the oilwhich is traveling in the oil-channels.

The burner rests removably upon standards I sides of said supports, andthe spreader is held in place upon said supports by being passed betweenupwardly-extending pairs of lugs 22 thereon .and having alsodownwardly-extending lugs 23, preventing lengthwise movement of thespreader. Thus all the parts can be assembled in a few seconds of timeand can be detached with like rapidity.

Great difficulty has heretofore been experienced with oil-burners inkeeping the same cleaned from the deposition of carbon andnon-vaporizable ingredients in the conduits of the oil-burner. It hasbeen the main object of my invention to provide a burner whichwhileabsolutely non-leakable shall permit'of cleaning of the passages ofthe oil very readily. It will be seen that the four main parts of theconduit along which the oil travels can be opened from end to end. Theyare normally closed either by short pipes 24, as shown in Fig.1, or byplugs 25, as shown in Fig. 8. Both the pipes and the plugs, however, canbeunscrewed, and when unscrewed the side con-- duits andthe end conduitswill be open from end to end, so that a brush or other suitable cleaningdevice can be passed freely therethrough and the same can be thoroughlycleaned. The short conduit in the bridge is also closed at its end by ashort pipe or by a plug, so that any deposit therein can be pushedforward by a brush and will fall into the vertical channel in thedownward extension 10, from which it can be removed by unscrewing a plug26 .closing said vertical channel. In the modification shown in Figs. 1to at the ends of these side and end passages are closed by shortlengths of pipe '24, having end caps 27 thereon.

The ob-. ject of this is to permit any residuum or oil that cannot bevaporized to be forced by the current into said pipes, which thus serveas receptacles for heavy or non-vaporizable oil and other residuum andpermit of the: oil-burner being used for a much longer period withoutcleaning, since such residuum can be collected in said short pipeswithout screwed short pipes 28, closed by caps, said pipes also servingto catch the residuum and non-vaporized oil and receive and hold thesame until it is necessary to clean the burner.

By providing the body of the burner with these closed-ended projectionsand locating them adjacent to or virtually in the path of the flamesfrom the gas-orifices and the deflectors it is evident that the oil orgas which is forced into them by the process of volatilization will besubjected to a greater degree of heat than would be possible if it werenot thus held substantially stationary before it returns to the mainportion of the conduit on its way to the gas orifices. In the cheaperform of burner shown in Fig. 8. however, such short pipes are dispensedwith, and the ends of the side and end passages are closed merely byplugs.

. The base-plate is made to incline downward toward the center from allsides, as shown, so that oil which is poured thereinto to start the firewill burn with the greatest efficiency for that purpose.

I claim- 1. Inan oil-burner, an angular body having a continuous conduittherein, the ends of which conduit at the angles cross each other andextend to the exterior of the body, said body being perforated upon itsunder side to communicate with said crossings, stoppers in saidperforations and in the end of the conduit, an extension depending fromthe body and provided with oppositely-extending perforated pipes, and aremovable deflector on top of the body the ends of which extend be- Inlike manner in said modifi cation the yond the body, and are eachprovided with a plate directly above one of the perforations in saidpipes, substantially as described.

2. In an oil-burner, a rectangular body provided with acentrally-located bridge, said bridge being perforated a portion of itslength and provided with a hollow depending extension communicating withsaid perforation,

said body having also acontinuous circuitous conduit, the ends of whichcross each other at'the corners and extend to the exterior of said bodyand the intermediate portions communicate with an oil-supply and withthe perforation in the bridge, respectively, the body being perforatedupon its under side to communicate with the conduit at said crossings,elongated cap-like hollow stoppers in said perforations and in the endsof the conduit, oppositely-extendingperforated pipes in the extension ofthe bridge, and a removable deflector above the body, each end of whichis provided with a plate directly above one of the perforations in saidpipes, said perforations and plates being exterior of the body andwithin the vertical plane of said stoppers, substantially as described.

3. In an oil-burner, a hollow body provided with laterally-extendingclosed-ended hollow projections, perforated pipes communicating withsaid body on its lower side, said perforations lying beyond said bodybut within the vertical plane of said projections, and a spreader on thebody, each end of which is provided with a plate directly above one ofsaid perforations, substantially as described.

4. In an oil-burner a hollow body provided with pairs of standards ontop, and a hollow extension onits bottom, having gas -orificescommunicating therewith, a support removably carried on each pair ofstandards provided with lugs engaging the standards and preventinglongitudinal movement of the support and having also lugs for engagingthe spreader, and a spreader removably carried on said supports, theintermediate portion of which is provided with lugs for engaging saidsupports and each end of which is. provided with a plate directly aboveone of said orifices, substantially as described. 7

5. In an oil-burner, a hollow body provided with pairs of standards ontop and a hollow extension on its bottom, having gas-orificescommunicating therewith, a support on each pair of standards providedwith lugs, and a spreader on said supports, the intermediate portion ofwhich is provided with lugs for engaging with said supports and each endof which is provided with a plate directly above one of saidgas-orifices, substantially as described. 6.
